Despite complaints on social media about the show being awash with familiar faces from gritty crime drama Love/Hate, this clip of the second instalment gives us our first glimpse of Laurence Kinlan as Tony Gregory.

Charlie is seen attempted to persuade Gregory for his vote.

This week's episode is due to cover 1982, the GUBU period.

GUBU relates to a phrase paraphrased from Charlie Haughey - grotesque, unbelievable, bizarre and unprecedented - and the acronym GUBU was coined by Conor Cruise O'Brien.
